Saul ‘Canelo’ Alvarez and Gennady Golovkin announced their fight in May

But he vowed at the time that he feared no man and would one day battle the Kazakh – on his own terms – and he has stayed true to his word and agreed signed up for the colossal fight.

Canelo will be 27 when the fight happens giving the advantages of youthful exuberance and freshness over the baby-faced 35-year-old.

Golovkin owns the middleweight division – he has destroyed British stars like Matthew Macklin, Martin Murray and Kell Brook – and has not needed to jump into different divisions to make money or his name.

He did threaten to boil down to super welterweight for a mega-money fight with Floyd Mayweather but Money Man appears too busy goading Conor McGregor on social media to slip the gloves back on.

Canelo, however, has used his ability to gain and shift huge amounts to his advantage.

Wins have come at welter, light middle and middle and he is rumoured to be able to pile on as much as 20lbs between the final weigh-in and first bell, making any mention of their weights now seem futile.

Unlike a lot of fights this needs no trash talk, social media campaigns or promotional tools. It is both the purists dream and the fair-weather fan’s ideal. It will be a fight for the ages.
